NW's Industrial (MBR) Membrane Bioreactor System

NW Systems’ Industrial (MBR) membrane bioreactor uses external crossflow type ultrafilter membranes that have over three times the flux as the hollow fiber alternatives (60- 90 GFD vs. 20-25 GFD for hollow fibers).

Higher Flux

Higher flux means less membrane surface area, ultimately saving capital cost on your project. Bioreactor aeration alternatives include coarse bubble aeration for commercial systems or, for higher strength industrial waste, the use of more efficient jet aeration for power savings in deep tanks.

Better Membranes

NW's (MBR) membrane bioreactor uses true UF Filtration, with 0.03 micron cross flow tubular membranes. Others use microfiltration (MF) with pore sizes 0.1- 0.4 micron, allowing more contaminants to make their way across the membrane surface. Nordic Water LA has installed over 500 membrane systems providing wastewater solutions since 1979. Combining sound engineering and process design with state of the art materials of construction has produced the membrane bioreactor.

(MBR) Membrane Bioreactor Benefits

3-4 times the flux of other systems in a smaller footprint
Lower Capital Costs
Tubular non-clog design reduces cleaning requirements
Automatic Operation
No Clarifier upsets
Much higher performance than conventional systems

Applying (MBR) Membrane Bioreactor to Industrial Wastewater

The membrane biological reactor (MBR) configuration has proven to be optimal for treatment of many industrial wastewaters when treatment efficiency is an important consideration.

The (MBR) membrane bioreactor is the ideal bioreactor configuration for treatment of organic or inorganic contaminants present in industrial wastewaters. MBR’s operate at a higher efficiency while achieving consistent design performance objectives. This makes MBR a more cost effective method of treatment when performance and tank requirements are considered.

Bioreactor systems such as the conventional activated sludge system, sequencing batch reactor system and trickling filters are typically designed for operation at a lower volumetric removal rate, requiring larger tanks and more space. These conventional systems often experience upsets that inhibit settling and therefore require much more operator attention than a membrane bioreactor.

The membrane bioreactor has proven to be optimal for treatment of many industrial wastewaters because it is less susceptible to upsets. The Membrane Bioreactors (MBR’s) performance is not affected by changes in sludge settleability like the conventional systems, making MBR a wise choice for industrial systems that have more difficult to treat waste streams. Dynatec has been dealing with difficult to treat industrial wastewaters using membrane filtration since 1979.
